How to display Item from a Listview by position in Android

Question

I want to display the item from a Listview by it's position. For Example: If i clicked on 3rd position i need to display the 3rd item. Here is my code. I want to display when the Item button is clicked.

 for (int k = 0; k < jsonarrays.length(); k++) {
          JSONObject main_menus = jsonarrays.getJSONObject(k);
          SUB_MENU_ID = main_menus.getString(TAG_SUB_MENU_ID);
          SUB_MENU_NAME = main_menus.getString(TAG_SUB_MENU_NAME);
          HashMap<String, String> submenu = new HashMap<String, String>();
          submenu.put(TAG_SUB_MENU_ID, SUB_MENU_ID);
          submenu.put(TAG_SUB_MENU_NAME, SUB_MENU_NAME);
          submenus.add(submenu);
 }
 @Override
 protected void onPostExecute(String result) {
      submenuadapter = new SubmenufoodCategoryAdapter(submenus, getActivity());
      sb_list.setAdapter(submenuadapter);
      sb_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

         }
      });}

And this is My Adapter Class.:

public class SubmenufoodCategoryAdapter extends BaseAdapter {
    ArrayList<HashMap<String, String>> mainmenu;
    HashMap<String, String> mainmenumap = new HashMap<String, String>();
    Context con;
    public SubmenufoodCategoryAdapter( ArrayList<HashMap<String, String>> submenu, Context con) {
        super();
        this.mainmenu = submenu;
        this.con = con;
    }
    @Override
    public int getCount() {
        return mainmenu.size();
    }
    @Override
    public Object getItem(int position) {
        return position;
    }
    @Override
    public long getItemId(int position) {
        return position;
    }
    @SuppressLint("ViewHolder")
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final Holder holder = new Holder();
        LayoutInflater layoutInflater = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mainmenumap = mainmenu.get(position);
        View rowview;
        rowview = layoutInflater.inflate(R.layout.submenu_button, null);
        holder.btn = (Button) rowview.findViewById(R.id.submenu_layout_button);
        holder.btn.setText(mainmenumap.get(FoodMenuItemFragment.TAG_SUB_MENU_NAME));
        return rowview;
    }
    public class Holder {
        Button btn;
    }
}

Don’t compare this code with your requirement.. I am just giving you Idea..

I think You are trying to inflating all data from adapter to List-view .. I made a sample where I am displaying all details from adapter to List-view inside a Dialog so

    builder.setAdapter(notes_second_adapter,
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int position) {

                    notes_child_category_second.setText(notes_second_list
                            .get(position).get(KIDZDAY_TAG_DESCRIPTION));
                    acti_id_to_save = notes_second_list.get(position).get(
                            KIDZDAY_TAG_REF_ID);
                    //sampel_1 = "Nihal Srivastava";

                }
            });

    dialog = builder.create();
    dialog.show();

Here You can see. after getting data into adapter you can call ArrayList.get(position).value of that field.. By your click it will fetch data according to position

You can give try to the following code snippet:

sb_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    //save data form here to some variables and on button click send data to where you want to show whether in new activity or something else

             sbmenus.get(2).get(FoodMenuItemFragment.TAG_SUB_MENU_NAME);

                 }
            });}

You can use a AlertDialog. Here is an example, answer 2.

public void dialogBox(String message) {
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
    alertDialogBuilder.setMessage(message);
    alertDialogBuilder.setPositiveButton("Ok",
        new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
        }
    });

    alertDialogBuilder.setNegativeButton("cancel",
        new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface arg0, int arg1) {

        }
    });

    AlertDialog alertDialog = alertDialogBuilder.create();
    alertDialog.show();
}

Call the dialogBox(String) method on your itemClick(), with the data you want to display.
